Forgot to add /etc/sysctl.conf:

# grep -Ev "^#|^$" /etc/sysctl.conf
security.bsd.see_other_uids=0
kern.maxvnodes=200000
security.bsd.unprivileged_read_msgbuf=0
net.enc.out.ipsec_bpf_mask=0x00000003
net.enc.out.ipsec_filter_mask=0x00000001
net.enc.in.ipsec_bpf_mask=0x00000001
net.enc.in.ipsec_filter_mask=0x00000002
